【问题描述】：
我正在创建一个自定义用户模型。
我运行了命令python manage.py makemigrations accounts，然后运行python manage.py migrate accounts，它输出以下错误：
Traceback (most recent call last):
File "manage.py", line 22, in <module>

connection.alias,
django.db.migrations.exceptions.InconsistentMigrationHistory: Migration admin.0001_initial is applied before its dependency accounts.0001_initial on database 'default'.
这是我的用户模型：
from __future__ import unicode_literals
from django.db import models
from django.utils import timezone
from PIL import Image
from django.contrib.auth.models import (
AbstractBaseUser,
BaseUserManager,
PermissionsMixin
)
class UserManager(BaseUserManager):
def create_user(self, email, username, password):
if not email:
raise ValueError("Users must have an email.")
user = self.model(
email=self.normalize_email(email),
username=username
)
user.set_password(password)
user.save()
return user
def create_superuser(self, email, username, password):
user = self.create_user(
email,
username,
password
)
user.is_staff = True
user.is_superuser = True
user.save()
return user
class User(AbstractBaseUser, PermissionsMixin):
email = models.EmailField(unique=True)
username = models.CharField(max_length=40, unique=True)
avatar = models.ImageField(blank=True, null=True)
date_joined = models.DateTimeField(default=timezone.now)
is_active = models.BooleanField(default=True)
is_staff = models.BooleanField(default=False)
objects = UserManager()
USERNAME_FIELD = "email"
REQUIRED_FIELDS = ["username", "password"]
def __str__(self):
return "@{}".format(self.username)
def get_short_name(self):
return self.username
这是应用程序中唯一的迁移文件：
from __future__ import unicode_literals
from django.db import migrations, models
import django.utils.timezone
class Migration(migrations.Migration):
initial = True
dependencies = [
('auth', '0008_alter_user_username_max_length'),
]
operations = [
migrations.CreateModel(
name='User',
fields=[
('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')),
('password', models.CharField(max_length=128, verbose_name='password')),
('last_login', models.DateTimeField(blank=True, null=True, verbose_name='last login')),
('is_superuser', models.BooleanField(default=False, help_text='Designates that this user has all permissions without explicitly assigning them.', verbose_name='superuser status')),
('email', models.EmailField(max_length=254, unique=True)),
('username', models.CharField(max_length=40, unique=True)),
('avatar', models.ImageField(blank=True, null=True, upload_to=b'')),
('date_joined', models.DateTimeField(default=django.utils.timezone.now)),
('is_active', models.BooleanField(default=True)),
('is_staff', models.BooleanField(default=False)),
('groups', models.ManyToManyField(blank=True, help_text='The groups this user belongs to. A user will get all permissions granted to each of their groups.', related_name='user_set', related_query_name='user', to='auth.Group', verbose_name='groups')),
('user_permissions', models.ManyToManyField(blank=True, help_text='Specific permissions for this user.', related_name='user_set', related_query_name='user', to='auth.Permission', verbose_name='user permissions')),
],
options={
'abstract': False,
},
),
]
我以前从未遇到过此错误，不知道如何进行。我该如何解决这个问题？

似乎您在应用管理员迁移后更改了用户模型。请阅读Changing to a custom user model mid-project。
